Clinical testing summary

Which under-eye serums have been clinically studied? Here’s a look at the available research.

• Plexaderm Rapid Reduction Serum was clinically studied on 43 participants using the VISIA® system, showing a visible reduction in under-eye bags, dark circles, and wrinkles within 10 minutes, lasting up to 8 hours. 
•  Dr. Brandt No More Baggage is clinically tested, but no specific study details are available.
• Peter Thomas Roth Instant FIRMx, Instantly Ageless, and Serious Skincare Insta-Tox do not publicly list clinical testing details.

Note: A "clinical study" provides measurable data, while "clinically tested" is a broader term that may not indicate rigorous testing.

1. Plexaderm vs. Dr. Brandt

Both Plexaderm and Dr. Brandt No More Baggage promise to reduce under-eye bags and puffiness fast—but how do they compare?

Features & Benefits

• Plexaderm is a lightweight gel that uses silicate minerals to create a temporary tightening effect, visibly smoothing under-eye bags and wrinkles.
• Dr. Brandt No More Baggage is a gel-cream that combines Filmatrix technology, caffeine, and peptides to instantly tighten, depuff, and brighten dark circles. It creates a second-skin film that visibly reduces under-eye concerns within minutes.

How They Compare?

• Which Works Faster?  Both deliver fast results. Plexaderm excels at firming and smoothing wrinkles, while No More Baggage also targets dark circles with its caffeine-peptide blend.
• Price & Value: Plexaderm is the more cost-effective choice for an instant firming effect. No More Baggage may offer added skin benefits over time, justifying the higher price for some users.

Key Differences

• Choose Plexaderm if you need a quick, firming effect for wrinkles and puffiness.
• Go with Dr. Brandt No More Baggage if you want a solution that also targets dark circles while depuffing the under-eye area.

2. Plexaderm vs. Insta-Tox

Both Plexaderm and Serious Skincare Insta-Tox promise instant wrinkle reduction, but they work differently.

Features & Benefits

• Plexaderm uses silicate minerals to create a temporary tightening effect, smoothing under-eye bags and fine lines.
• InstaTox relies on peptide technology to firm and tighten the skin on the face and under-eye area, while also delivering hydrating benefits.

How They Compare?

• Which One Layers Better? Insta-Tox can work well with other skincare products or makeup, but proper layering is essential. 
• Affordability: Insta-Tox is a budget-friendly option, often available in multi-pack deals. Plexaderm is slightly pricier per application but is popular for its longer-lasting results.

Key Differences

• Choose Plexaderm for a longer-lasting tightening effect.
• Go with InstaTox if you want something more budget-friendly that layers well with makeup. 

3. Plexaderm vs. Instantly Ageless

Both Plexaderm and Instantly Ageless promise to reduce under-eye bags and wrinkles—but they use different ingredients and methods to achieve their effects.

Features & Benefits

• Plexaderm is a silicate-based tightening gel that temporarily firms skin within minutes.
• Instantly Ageless is a peptide-based microcream that tightens the skin using Argireline, which helps relax facial muscles and smooth expression lines. Note: A sample pack is available for purchase.

How They Compare?

• Speed of Results: Both work within minutes, but Plexaderm focuses on firming, while Instantly Ageless relaxes fine lines and tightens skin like Botox alternatives.
• How Long Do the Results Last? Plexaderm lasts 8–10 hours, while Instantly Ageless lasts around 6–9 hours but may leave a visible film if over-applied.

4. Plexaderm vs. Peter Thomas Roth Instant FIRMx

Both claim to tighten skin and reduce under-eye bags instantly.

Features & Benefits

• Plexaderm creates a temporary firming effect by forming an invisible film on the skin.
• FirmX uses sodium silicate and magnesium aluminum silicate to create a similar tightening effect.

How They Compare?

• Which One Lasts Longer? Curious about which product keeps your skin firm the longest? We put them to the test! See our in-depth Plexaderm vs Peter Thomas Roth longevity comparison here.
• Which One Blends Better? Plexaderm dries to a smooth, matte finish, while FirmX can sometimes leave a visible white residue if over-applied.

Key Differences

• Choose Plexaderm for a smoother, more natural finish.
• Go with Peter Thomas Roth if you want an all-over firming effect and don’t mind experimenting with application techniques.

5. Plexaderm vs. Preparation-H: Does this viral hack work?

I included Preparation-H in this list of puffy under-eye serums because, while it's not actually designed for this purpose, some people swear by its ability to reduce puffiness and wrinkles. Here is what Prep-H does and does not do.

Features & Benefits

• Plexaderm is a skin-tightening gel designed for under-eye use.
• Preparation H is a hemorrhoid cream that contains phenylephrine, which constricts blood vessels and temporarily reduces puffiness.

How They Compare

• Safety & Long-Term Use: Plexaderm is formulated for facial skin, making it a safer choice for repeated use.
• Effectiveness: Preparation H can reduce swelling but isn’t designed for delicate under-eye skin and may cause irritation. See what dermatologists say in our guide: The Truth About Preparation H for Puffy Eyes.

Key Differences

• Choose Plexaderm for a safe, long-term solution.
• Avoid Preparation H unless you understand the risks.

Serum Side Effects

Are these products safe for all skin types? While these serums deliver fast results, some users report temporary side effects, such as mild redness, sensitivity, or a tight feeling.

If you have sensitive skin, do a patch-test first and read the label, as manufacturers often indicate suitability for different skin types.

Which is right for you?

Not sure which product is right for you? Here’s a quick guide to help you decide.

For Instant, Dramatic Lift:

• Plexaderm – Strongest tightening effect, lasts 8–10 hours, best for deep under-eye bags.
• Peter Thomas Roth FirmX – Strong firming but can leave a white residue.
• Instantly Ageless – Best for expression lines and a photo-ready finish.

For Everyday with Flexible Finish:

• InstaTox – Firms without feeling overly tight, blends well under makeup.
• Dr. Brandt No More Baggage – Light firming, best for reducing puffiness and dark circles.

My review & application tips

I’ve personally tested all of these products in real-world conditions. Check out my Best Under-Eye Puffiness Product Reviews to see which ones truly work!

One simple trick makes tightening serums work better, especially for dry, aging, or sensitive under-eye skin:

• Apply a hydrating, non-oily eye moisturizer first to prevent serums from settling into fine lines.
• Wait 10 minutes for it to fully absorb.
• If the area feels oily or tacky, lightly dab with a tissue to remove excess.
• Apply serum with a light dabbing motion, don't rub.

This quick routine ensures smoother application, no residue, and better performance without irritation.

What else works for puffy eyes?

Under-eye tightening serums like Plexaderm, Instantly Ageless, Insta-Tox, and Dr. Brandt No More Baggage offer quick, temporary fixes for puffiness, fine lines, and wrinkles.

Each product works differently, some tighten, others depuff or smooth expression lines. The best choice depends on how long you want results, how well it layers under makeup, and whether you need hydration or extra firming.

But puffiness isn’t always from swelling.

Sometimes, it's a "jelly roll"—a small muscle bulge under the eyes—where Botox for under-eye puffiness may offer a longer-lasting fix.

In these cases, Botox for under-eye puffiness may be a better long-term solution for a smoother, more refreshed look.

In other cases, puffiness is actually volume loss, hollowness, or deep tear troughs. That’s when fillers for under-eye puffiness might be the better option.
